Answer:

DNA replication

Explanation:

Synthesis is the stage characterized by DNA replication. It is after the G1 phase

Most of the cell's time is spent in the interphase. The first growth phase comes first, then the synthesis phase, and finally the second growth phase. In the synthesis phase, DNA replication occurs. So the last option is correct.

The interphase is the preparatory phase of the cell before going into the division phase (M phase). The first phase is the G1 phase, or first growth phase, in which the cell grows in size. Then the cell enters the synthesis phase, or S phase, where the cell's genetic material, which is DNA, is replicated.

A single DNA molecule duplicates itself, but the two DNA molecules are linked by a single centromere. In  synthesis phase the centrosome replicates too, making two centrosomes. Then the cell enters the second growth phase, or G2 phase. Here the cell again grows for the division.

Hence, in the synthesis phase, DNA replication occurs. The last one is correct.

Answer:

0.2um

Explanation:

take each of the answers multiply by 40 and see which the answer is 8um

0.2×40=8um

The diameter of the bacterial; cell would be 0.02 micrometer therefore the correct answer is option A.

It is defined as the multiplication factor used for the design of an object with respect to some other object. the scale is generally used to design prototype designs of large objects.

It is multiplied by the design dimension to get the actual size of the object or product.

As given in the problem A red blood cell is 8 micrometers in diameter. If a bacterial cell is 40 times smaller, then we have to calculate and calculate the diameter of the bacterial cell.

scale factor = 40

diameter of the bacterial cell = 8 micrometers/40

                                                 = 0.02 micrometers

Thus, the correct answer is option A.

Explanation:

Answer:

In osmosis, molecules cross the cell's plasma membrane to achieve equilibrium.

Explanation:

A bilipid layer called a plasma membrane typically surrounds cells. Here, lipid molecules are arranged tail-to-tail, with their heads facing outwards. The heads of the lipids, are water soluble, while the tails are insoluble. Proteins and cholesterol also help maintain membrane fluidity.

With the use of its transport proteins, pores and gated channels, embedded among the lipids the membrane maintains its concentration of substances through selective permeability.

Simple diffusion occurs in cells through plasma membranes as a means of passive transport. In osmosis, molecules of water move across the membrane, down their concentration gradient- i.e. they try to balance their concentration or number of water particles.

The water particles move from regions of high concentration to regions of low water concentration. Typically these 'destinations' or regions have large amounts of solute which contributes to the formation of this gradient.

Answer:

The last one does not happen meiosis create four genetically different haploid cells

Meiosis, on the other hand, creates four distinct daughter cells, each of which has half as many chromosomes as the parent cell. Thus, option D is correct.

Meiosis is crucial for three reasons: it promotes genetic diversity, sexual reproduction of diploid species, and the correction of genetic flaws.

A parent cell undergoes mitosis, which creates two identical daughter cells with the same number of chromosomes.

Genotypic diversity is produced, and appropriate homologous chromosomal segregation is ensured via meiotic crossing over.

Despite these functions, very little is known about the genetic and population genetic mechanisms that resulted in the evolution of species-specific variations in recombination rates.

Therefore, process of meiosis produces two genetically identical cells.

Answer:

1: The higher the force applied to the ball, the harder to make a home run because of the third law: every action has a reaction, the reaction is absorbed by the bat.

2:Same equation: F=MA from the second law, if the ball has a higher mass, it will have a higher force.

Explanation:

The third rule, which states that every action has a response, which is absorbed by the bat, makes it tougher to hit a home run the more power is given to the ball.

Newton's laws of motion are three fundamental physical laws that describe the behavior of objects in motion and how they interact with forces. The laws were first published by Sir Isaac Newton in 1687.

Law of Force and Acceleration - The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. This law is often expressed as F=ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object.

Law of Action and Reaction - For every action, there is an equal and opposite reaction. This law states that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

In ginger, growth can be seen in the rhizome, it is a modified root. The rhizome grows the plant.

Growth is the constant expansion of an organism's size through time. It could also be described as one of a living thing's traits. "Biological growth" in biology refers to development that occurs throughout time. Throughout their lives, living creatures frequently expand. But it is a process that unfolds gradually and on a regular basis.

Typically, growth starts when a single cell is present. This cell may divide and enlarge in a particular area, as in plants, or it may diversify and enlarge over the entire organism, as in mammals.

The environment and internal elements have a large role in determining how rapidly or slowly an organism will grow. These variables have undergone centuries of change, changing how living things behave. Thus, growth can be in rhizomes in ginger.

D. Conjugation

Explanation:

Bacterial conjugation is the transfer of genetic material between Bacterial cell by direct cell-to-cell or by bridge like connection between two cells.

The process in which the formation of a bridge-like structure takes place between bacteria to exchange genetic material is known as conjugation and thus option D is correct.

Bacteria is a prokaryotic cell and it has developed various methods for the purpose of genetic recombination. Genetic recombination is significant for genetic diversity. The 3 most common methods used by bacteria for the diversification of their DNA are namely Transduction, Transformation, and Conjugation.  

The Conjugation process is explained as follows:

Thus, we can conclude that the conjugation process in bacteria can cause the formation of a bridge-like structure to exchange genetic material and option D is the correct answer.

Explanation:

The time it takes for an animal to metabolize a drug to a non-detectable levels could belongerthan that of the withdrawal period. Hence the correct option is A.

The metabolism of a drug refers to the process by which the body breaks down and eliminates the drug from the system. The withdrawal period is the time required after administering a drug during which the animal must not be slaughtered for human consumption to ensure that no residues of the drug are present in the edible tissues.

There are several factors that can influence the metabolism of a drug in animals, such as the drug's chemical properties, the animal's species, age, health status, and metabolic rate. Some drugs may be metabolized relatively quickly, while others may take longer to be completely eliminated from the system.

Hence the correct option is A.
